This invention relates to a wheel which can be adapted to mount a single tirecarrying rim or dual tire-carrying rims.

It is an object of the invention to provide a motor wheel. which can be quickly and easily changed from mounting a single tirecarrying rim to a wheel mounting dual the carrying rims. r

A further object of the invention resides in providing means for increasing the traction of the wheel when the dual tire rims are mounted thereon,

The above and other objects of the invention are achieved by the apparatus illustrated in the accompanying drawings and described below, being understood that'the invention is limited to theexact form thereof shown and described.

In the drawings v Figure 1 is a side elevation of a diametric half of a wheel embodying the invention with a single tire-carrying rim mounted thereon.

Figure 2 is a sectional view taken on line 22 of Figure 1.

9 i. 'le el vatio of a di-ametric lipuio o s a sic e c n 1a f of the wheel of Figures 1 and 2 but with dual rims mounted thereon.

Figu l is a sectional view taken on line of Figure 3. The numeral 10 indicates an integral. wheel, constructed in accordance with the in vention, which preferably comprises a hub 10, a radial flange 10 offset as at 10 and strengthened by ribs 10 and a longitudinally extending circumferential tongue The wheel 10 may have a brake drum 11 secured thereto.

A rim 12 which is formed with a bevel 12 thereon is carried on the wheel 10 by cooperation of the bevel 12 with the slightly tapered edge to the offset flange 10. A plurality of bolts 13 spaced circumferentially about the wheel flange 10 serve to force clamps 14 against the rim 12 to hold it tightly on the wheel.

In changing the wheel 10 to mount dual tire-carrying rims, the bolts 13 and clamps 1a of the single rim type shown in Figures 1 and 2 are removed and a circular weight is secured to the wheel 10 by bolts 21, the

nuts of which are received in the weight 20 in recessed portions 20 of a longitudinally extending circumferential rib 20 whose outer periphery is tapered as at 20 As illustrated in Figure at the face of the weight 20 adjacent the wheel 10 is appropriately formed to lit with the wheel surface to give a solid integral weighted wheel structure. The diameter ofthe weight is such that the rim 12 will just slide thereover in tire changes.

A second rim 22 formed with a bevel 22 is adapted to be carried 011 the weight 20 and is spaced from the rim 12 by a U-shaped spacer ring 23. A wedge ring 2 1 sliding on the tapered surface 20 of the weight '20 is provided to cooperate with the bevel 22 of the rim 22 and is clamped in place by a plurality of stud bolts '25 secured in the weight 20. The clamping action of the wedge ring 24 acting through the rim 22 and spacer 23 forces the rim 12 tightly against the flange 10 to hold it securely in. place. The wedge ring 24 also forces the rim 22 tightly against the spacer 23 and this in conjunction with the wedging action thereof also securely clamps the rim 22 on the wheel.

lt'will be, understood that any type rim may be used in thepractice of the invention as long as a suitable bevel or shoulder is provided thereon to cooperate in the manner above described. In the type of rim illustrated the bevels 12 and 22 also form gutters for locking rings 15which hold side rings 16 on the rims.

The present invention allows a wheel to be readily converted, with but little extra equipment, from a dual rimmed to a single rimmed wheel or vice versa. The change can be made by the unskilled workman with simple tools.

The wheels of the invention are particularly adapted for use with tractors or like vehicles where at certain times, such as when used on pavement or the like, a single tirewill be, suflicient, but which vehicles at other times, when used on soft or yielding ground, require additional support and traction, thus necessitating a dual tired wheel. While the invention can be used on eitherdriving or e to have the extra surface and traction the wheel may readily be changed back to the single rimmed wheel as will be understood.

In the practice of the invention it will be evident that at all times the weight 20 will not be necessary in the dual wheel and that it may take the form of a relatively light extension ring, identical in form with the Weight, but whose inner periphery is shown by the dotted line 50.- The extension ring will function, except for the increased traction due to the weight, exactly similar to the weight.

As many other changes could be made in the construction, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative only and not in' a limiting sense, accordingly various modifications and-applications of the invention can be resorted to without departing from the spirit of the invention or the scope of the appended claims.

What is claimed is:

1. In combination, a wheel having a peripheral rim seat, a first tire carrying rim mounted on said seat, an annular traction increasing weight secured to the wheel to project axially from said seat and first rim, a second tire carrying rim adapted to be positioned so as to project, for the major engaging said seat in an offset position so as to be axially centered with respect to the hub, an annular weight member mounted on said radial flange to project axially beyond said hub in the "direction of ofiset of said rim seat, a second tire carrying rim adapted to be supported in an offset position on the projecting portion of said weight member so as to project axially beyond said member, and means for securing the rims in the relative positions mentioned comprising means acting on said second mentioned rim and through it to the first mentioned rim to secure the latter on its seat.
